2019-10-14  Thomas Koenig  <tkoenig@gcc.gnu.org>

	PR fortran/92004
	* array.c (expand_constructor): Set from_constructor on
	expression.
	* gfortran.h (gfc_symbol): Add maybe_array.
	(gfc_expr): Add from_constructor.
	* interface.c (maybe_dummy_array_arg): New function.
	(compare_parameter): If the formal argument is generated from a
	call, check the conditions where an array element could be
	passed to an array.  Adjust error message for assumed-shape
	or pointer array.  Use correct language for assumed shaped arrays.
	(gfc_get_formal_from_actual_arglist): Set maybe_array on the
	symbol if the actual argument is an array element fulfilling
	the conditions of 15.5.2.4.
